TSA6057 Philips Receiver Synthesiser on a Chip This is from an abortive monitor receiver project. Only a very few external components are needed. This is the easy to use conventional plastic dual in line. Ideal for VHF receivers. A simple PIC or Arduino Mini can be used to program this with a single of multiple frequencies.I am selling a lot of components and radio and Hi Fi parts and units that I have collected over the very many years !!ThanksDave G4IUG
